Tu as mis du WPA1 au lieu du WPA2 ?

J'aimerais les avis des collègues, sur un paquet linux-oem-osp1.

Salut (re pour xubu )
Honnêtement, je n'y crois pas trop dans ce cas, puisque les conditions sont différentes. Après, différences ne veut pas dire que ça ne fonctionnera pas.

On peut essayer (regarde et donne toutes les dépendances qui sont installées, afin de pouvoir nettoyer le cas échéant...)

zephirin · Le 20/02/2020, à 08:20

Je précise que ça fonctionne mais c'est long à se connecter et lent à naviguer.

Donc à moitié solutionné mais pas plusieurs onglets à ouvrir sinon ça rame encore plus !

Si je pouvais trouver un carte mini=PCIe qui ne pose pas problème.

J'ai vu qu'il y a un autre modèle, encore Intel, la 7260.

Vous avez des retours positifs sur cette carte ?

@Nico

Vu l'ordi de zephirin :

 dell-Inspiron-5558

C'est pourquoi je soumets l'idée des paquets spécifiques linux-oem-osp1 et à tester éventuellement avec la carte :

Au #1 a écrit :

Intel Dual Band Wireless-AC 8265 NGW provenant d'un Lenovo T480 qui a été "Hackintoshisé".

Au vu de : 7260 et 7265 ne seront pas pris en charge par les dernières versions de firmware

zephirin · Le 20/02/2020, à 09:46

Ok merci pour ton implication et celle des autres aussi bien sur !

Donc je n'ai que 3 solutions :

1/ je reste comme ça avec cette carte boiteuse
2/ j'ai l'option de la clé USB
3/ je cherche une carte compatible

Des retours sur la 7260 ?

zephirin · Le 20/02/2020, à 09:56

Oui, ... maintenant !

zephirin · Le 20/02/2020, à 09:56

Il doit bien y avoir d'autres cartes compatible, non ?

xubu1957 · Le 20/02/2020, à 09:59

Tu l'avais testé la 8265 ?

Oui, (1er post).

Il faut que je change la carte donc.
